CVE-2026-11998Public exploitNetwork attack vector

XSS via ungrouped SCE regular-expression alternatives

Published Jun 24, 2026 · Updated Jun 24, 2026

Cross-site scripting in Google AngularJS 1.2.0-rc.3 and later allows remote attackers to execute JavaScript through resource URLs. The SCE delegate anchors a configured regular expression without grouping its alternatives, so a crafted URL can pass when only one alternative matches partially. Exploitation requires an application to use an alternation-bearing resource URL matcher and a victim to load attacker-controlled input; execution remains within that application's browser origin.
